In one study, a subtracted gene expression analysis in dendritic cell subsets revealed differential expression of members of the SIRPβ family, which are implicated in ligand‐dependent phagocytosis regulation. This work underscored that specific membrane proteins expressed selectively on CD8(–) conventional dendritic cells could mediate targeted uptake of pathogens, yet no role for SNORA74A was delineated."}, {"type": "fg", "children": [{"type": "fg_f", "ref": "1"}]}, {"type": "t", "text": ""}]}, {"type": "t", "text": "\n\n"}, {"type": "p", "children": [{"type": "t", "text": "\nAnother investigation focused on the engagement of SIRPβ proteins expressed by various hematopoietic cells.
